Oracle Database Express Edition (XE)

I am using Oracle 10g XE. I wanted to completely remove the sample HR database so that I could create my own database.. So I followed these instructions:


sqlplus / as sysdba

SQL> shutdown immediate;
oracle database closed
oracle database dismounted
oracle instance shutdown

SQL> startup restrict mount;

SQL> drop database;

Database dropped

SQL> exit



So my question now is, how do I recreate a new database? Also, I am so confused - I can't even load the Oracle 10g XE Home Page. Why not? Why does a database have to exist for me to be able to open up the database admin tool? That doesn't make sense to me. I feel like I broke everything, lol. Help! Thanks.
